Application filed October 6 1899.

T0 all whom, t may concern:

Be it known that I, HENRY T. MASON, a citi# zen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Oiling Mechanism, ofwhich the following is a specication, reference be# ing hadtherein tothe accompanying drawing.

The invention has relation to an improvedv type of oiling mechanismparticularly designed for use in oiling verticalshafting; and theinvention consists in the novel construction of the mechanism referredto, as Will be more fully hereinafter shown and described.

The drawing is a vertical central section through a shaft, illustratingmy improved oiling mechanism therefor.

The reference-letter A designates a vertical shaft, in which is formed acentral bore B and counterbores O and D, and Within the shaft at thejunctions of the bores are arranged a series of plugs 'E of a sizecorresponding to their respective bores, as shown. These plugs dividethe interior of the shaft into a series of reservoirs adapted to befilled with oil and provided with means for distributing the oil to theshaft at different parts of its length for the Apurpose of oilingpulleys, gear-wheels, dac., that may be arranged upon the shaft forrotary movement.

The letters F and G designate two bandwheels sleeved upon the shaft andheld in their respective positions by means of collars H. These wheelsare lubricated by the following means: Each reservoir is provided withan oil-inlet passage I and an oil-discharge passage J, these passagesbeing preferably arranged, respectively, one above the other and leading-from the reservoir to 'the periphery of the shaft.

K designates bores of considerably-smaller diameter than theoil-passages, which are formed in the shaft extending from substan-ytially the middle of each lower oil-passage in a diagonal direction tothe shaft-periphery,

in the periphery of the shaft, with which the small bore communicates.

M designates oil-cups secured within the upper passages of thereservoirs, and O represents threaded plugs within the lowerdischarge-passages adapted to control the flow .a single bore wereformed.

serai No; 732,778. (No modem agonal bore.

From the description of the mechanism thus set forth it will be observedthat by forming counterbores in the center 0f the shaft in the mannerset forth I am enabled to partition off the interior of the shaft bymeans of the plugs in a more ready manner than if This follows from thefact that the plugs constituting the partitions only have a driving fitwith the bores that they are intended to engage with, thus dispensingwith the necessity of forcing the plugs the entire length of the shaft;also, by forming these oil-reservoirs Within the shaft I am enabled tokeep a large supply of oil on hand, which by means of the plugs O may bedistributed to a nicety to the rotating gears or hand-wheels upon theshaft.

The mechanism as thus far described is shown to be applied to astationary shaft. It will be obvious, however, that the same mechanismmay be applied to a vertical shaft that is mounted for rotary movement,as in case of mill-spindles. I have therefore shown the shaf t asconstructed for rotary movement with my improved oiling mechanismapplied thereto.

P designates a base or step in which a socket Q is arranged, and withinthe socket the' end of the shaft extends. The diagonal bore K in thiscase leads from the lower passage of the reservoir to a point within thesocket, whereby the contacting surfaces of the socket and shaft arethoroughly lubricated. I have also provided small diagonal apertures R,leading from the lower reservoir in the shaft to the base of the latter,whereby the shaft end may be lubricated. Also I preferably interposebetween the said shaft end and the socket a tempered plate S,constituting a bearing for the shaft.

What I claim as my invention is- 1. The combination of a shaft having acentral bore formed therein'constituting an oilreservoir, a transverseoil-passage leading from the periphery to the central bore, and adiagonal bore extending from the transverse passage Vto theshaft-periphery;v a plug, ar-

ranged within andoccupying a portionvonly of the transverse passage,said plug having its inner end located at substantially the j uncof theoil from the reservoir through the di@ IOO g v 648,212V

tion of said passage and the diagonal bore and adapted to control theiow of the lubricant through said diagonal bore, and an oil- 'cupcommunicating with the interior of the shaft, substantially asdescribed.

2. The combination of the shaft having a central bore formed thereinconstituting an oil-reservoir, an upper and a lower transverse passageleading from the periphery of the shaft to the interior of the latter,and a diagonal bore extending from substantially the central portion ofthe lower transverse passage to the shaftperiphery; an adjustable plugarranged within and occupying a portion only of the lower transversepassage, said plug having its inner end located at substantially thejunction of said transverse passage and the diagonal bore, and adaptedto control the flow of the lubricant through said diagonal bore, and anoil-cup communicating with the upper transverse passage.

3. The combination of a shaft having a cen tral bore and a multiple ofcounterbores formed therein, plugs within the shaft at the junction ofthe bores dividing the interior of the shaft into a seriesvof centraloil-reservoirs, each provided with an upper and a lower oilpassage,leading from said reservoir to the shaft-periphery, and the shaft havingformed therein amultiple of diagonalbores of smaller diameter, one foreach reservoir and leading from the lower passage of the reservoir tothe shaft-periphery at a' point below the reservoir, an oil-cupcommunicating with the upper oil-passage of each reservoir, and ascrewplug Within each lower passage controlling the ioW of the oilthrough the diagonal bore.

In testimony whereof I aix my signature in presence of two witnesses.

HENRY T. MASON.
